WATER-HEATER FOR GAS-STOVES. 4

SPECIFICATION forming part of Letters Patent No. 519,050, dated May 1, 1894.

Application filed May 31, 1893. Serial No. 476,190. (No model.)

.To and whom it may concern:

Be it known that I, LAURA MA IA STONE, of Rochester, New York, have invented an Im-' provement in Water-Heaters for Gas-Stoves,

of which the following is a specification. i

The invention relates to water heating devlces for stand boilers and tanks; and its object is to increase the efiiciency of such ap paratus, and to adapt a water heating gas stove to be placed on either side of an ordi nary range or stove whether brick-set or not and communication of the Water pipes of the gas stove to communicate with the'usual water heating devices of a range and also with the water tank; and the invention consists in the construction hereinafter described and particularly pointed out.

My improvements in water heaters are represented in-the accompanying drawings, in which- Figure 1 is a perspective view of a water heater, boiler or tank and range combined the front and top of the gas stove being removed. Fig. 2 is a partial plan of the gas stove.

The reference letter K denotes a stand boiler or water tank, G a range or stove having a water heating coil or water back.

A is a gas stove having ovens 'E and F and three compartments above a partition or floor U separated by partitions M and having each an exit to or w formed by an offset 2 in a partition and leading to an escape flue D.

c and d denote gas burners and R and S removable partitions.

r r is a partition in the space between the floor U and ovens E adapted to direct products of combustions from the burners (1 up through openings to from which they pass to an exit to leading to the chimney or flue D.

A water heating -coil is denoted by j k, which at t' is coupled to pipes L and J leading respectively to the stand boiler or tank K and to' a water back or coil in a range G. The water heating coil is situated near the stove top. The part j surrounds the pot holes in a side compartment and the part Icissituated beyond the burner and pot hole and near to the exit in the middle compartment so as to interfere as little as practicable with the heating of vessels placed in or over said holes. The burners c are placed at a. little I lower level than the coil and immediately under the cooking holes and laterally within the bends of the coil as shown. By this construction the hot gases from the burners are mainly and first utilized to heat cooking-vessels and then passed over and above the water pipe ,thereby economizing heat which might otherwise be carried up the chimney. There may be two gas burners c ineach side compartment and one in the middle compartment,'but in this drawing the two gas burners in one side compartment are omitted. The middle compartment receives all the escape ing hot products from the roasting oven burners d, d, through the openings :1: w in the floor of the middle compartment. Thus five separate burners can be made to heat the water.

Notches m are provided in each side wall of the stove, near the back and also in each partition M. The heating coil j, 10, is laid in these notches, and is provided with a detachable supporting bracket Z, fastened to a partition M. This support also closes tightly the notch m in the partitionr The other notches will have fittings to suitably close them after the water heater has been laid in place as indicated by dotted lines. These fittings will hold the water heating coil firmly. If more convenient to place the gas stove on the other side of the range G the coil 7,10, can be suitably connected with the same and placed in the compartment at the opposite side of said gas stove. In this case the support Z will be removed to the partition M opposite that on which it was before situated.

' Where no coal range is used, the gas stove being used for all the cooking, and the kitchen warmed in winter by the house heating furnace, or other heater, the gas stove maystand on either side of the water tank, and all the change required, will be to put the water heater, in the side compartment next to the water tank.

Thetwo side compartments of the stove are alike and the side walls of the middle one are alike so that it'makes no difference in operation' in which side compartment the coil is situated or which side of the coil ,is uppermost. The front of the stove has an air inlet for each compartment and there is an exit in each .compartment to the chimney flue.

By the construction above described it is provided that the water heating coil of the gas stove can be connected with the water coil or water back of ordinary ranges provided with stand boilers and on either side thereof as desired or according as the range and its boiler are relatively situated.

With the front and top of the stove and the chimney flue pipe D, on,,and the cooking dishes down tightly on the boiling places, or the boiling places closed with covers, as in an ordinary coal range, sufficient heat will be obtained for heating the water in the tank.

The water heating coil can have the united heat of three boiling gas burners, and of both roasting oven gas burners, but if one burner only is used it will warm the water to some extent.

The usual hot water pipe, such as pipe J of an ordinary coal range, can be cut and an end thereof joined to one end of the heating coil of the gas stove and the other end of said coil connected with a pipe L, which communicates with the water tank.

Either one or both of the stoves will heat the water according as one or both are used.

My construction and arrangement which provides for passing water through coils in both stoves in a single and directly continuous manner is an improvement on the T coupling heretofore used to divide the current and divert the separate parts thereof simultaneously, to. diiferent structures. By the improvement water is caused to flow directly and continuously in full current through both stoves in a single stream and the water will thereby be kept fresh, and the pipes in good condition, and comparatively free from sediment.

I am aware that a stand boiler and range have been combined with a supplementary water heater having a shelf to support a heating lamp or the like the heater having a double connection both with the boiler and with the range and I do not claim such a combination, in which no provision is made for a single continuous circuit of water under all conditions of use. By my improved device the gas stove, range, and boiler have each but one possible direct communication with either of the others and no circulation is possible except it be equal and continuous through them all. Among other advantages of this improvement it is efiected that water circulates equally through the entire pipe system and obviates the deposition of sediment in any particular part. And further the danger of the freezing of water in a part of the pipe when disused by the disuse of one of the heating devices is avoided.

I am further aware that a supplemental water heating device has been combined with a stand boiler and range in such manner that the water circulation caused by the range fire passed through the supplemental heater, but in such combination no provision was made for compelling a circulation through the coil or water back ofthe range when the latter is not in use. It is essential that the construction be such that circulation is insured through both the range and the supplemental heater whether either one or both be heated. No claim is made to combinations to the particular form of gas stove or to comblnations specifying the ovens, burners and other like details of the stove illustrated herein as such matter forms the subject of my application filed August 13, 1892, and serially numbered 442,959.

Having thus fully described my invention, what I claim is- 1. In a water heating gas stove the combination of a stand boiler, a gas stove having two ovens E, F provided each with a burner said burners being situated in roasting ovens immediately beneath the first named ovens and having two compartments above the ovens provided each with a burner or burners, and a top having pot holes and a water pipe communicating with the boiler and extending under the stove top and into both compartments and having one or more coils in one compartment and in the other a part situated in the path of the products of combustion from the oven burners, substantially as set forth.

2. In combination with a tank and a gas stove having two compartments provided with burners and with pot holes in their top, the water coil comprising a partj provided with oneor more rings situated near the top said water coil comprising also a second part 7.: extending through a partition into another compartment and situated near its burner and pot hole, and the oven burners, said extension being arranged in the path of the products of combustion from said burners, substantially as set forth.

3. In combination the range having a water heating back or coil, a stand boiler or tank, the gas stove, the water heating coil of said gas stove, a pipe connecting the range coil with the boiler, a pipe connecting the boiler with the gas stove coil, and a pipe J connecting said gas stove coil directly with the range coil, the whole forming a continuous single circuit whereby water is compelled to flow in an undivided current through the pipes, boiler, range coil, and gas stove'coil whenever either the gas stove or the range is in use, substantially as set forth.

4:. In combination the range having awater heating back or coil, a stand boiler or tank, the gas stove, the water heating coil of said gas stove, a pipe connecting the range coil directly with the boiler, a pipe connecting the boiler with the gas stove coil and a pipe J connecting said gas stove coil directly with the range coil in a continuous single circuit whereby water is compelled to flow in an undivided current through all the coils, pipes, and the boiler said gas stove coil being provided with detachable couplings and the stove having notches and fittings whereby it is adapted to be placed on either side ofdthe range and tank and in connection therewith,-

lings and the continuously connected pipes I, J and L said pipe J connecting the 'gas stove and range coils directly whereby the IO water is compelled to flow in one circuit through all the coils, pipes and the boiler, said gas stove being adapted to admit lts water coil pipe connections and also gas burner connections on either side, substantially as set forth.
